AI Technical Summary

Benefits of technology

The thiazolium dyes effectively maintain fabric color without bluish tint accumulation, reducing the need for chlorine treatments and associated fabric degradation, offering a convenient and cost-effective solution for fabric care.

Problems solved by technology

For example, white fabrics which are repeatedly laundered can exhibit a yellowing in color appearance which causes the fabric to look older and worn.
Unfortunately, such hueing or bluing dye typically tends to accumulate on the fabric, thus giving the fabric an undesirable bluish tint.
While a chlorine treatment can be effective, it is an additional, inconvenient step in the laundry process.
Additionally, a chlorine treatment is costly and harsh on fabrics—contributing to increased fabric degradation.

No. 11 / 655,337 filed Jan. 19, 2007, which in turn claims priority under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 60 / 761,428 filed Jan. 23, 2006.FIELD OF THE INVENTION[0002]The present invention relates to thiazolium dyes, laundry care compositions comprising one or more thiazolium dyes, processes of making such dyes and laundry care compositions and methods of using same.BACKGROUND OF THE INVENTION[0003]Fabrics, typically lighter colored fabrics such as white fabrics, that are worn and / or laundered typically discolor. For example, white fabrics which are repeatedly laundered can exhibit a yellowing in color appearance which causes the fabric to look older and worn. In an effort to overcome such fabric discoloration, certain laundry detergent products include a hueing or bluing dye which attaches to fabric during the laundry wash and / or rinse cycle. Unfortunate...
